摘要
本文使用多波资料检测裂缝,根据上行转换横波穿过裂隙介质时产生的分裂特征来研究裂隙特征,采用旋转分析法识别裂缝方位,用NMO速度分析、纵横波垂直速度分析和旋转分析计算裂缝密度。对四川盆地LYS构造实际资料处理证明,多波资料是检测裂缝的有效手段,该方法具有很高的应用价值。
The paper presented a method for detecting fracture by multi-component technique. The S-wave splitting characteristics caused by upgoing converted S-wave transmitting fracture medium are used to study fracture property. The fracture orientation is detected by rotation analysis. The fracture intensity is detected using methods of NMO velocity analysis. vertical velocity analysis of P- and S-wave and rotation analysis. The real data processing of LYS structure in Sichuan losin reveal that fracture detection with multi-component data is effective and highly practical tool
